Images are not loading on production - ruby-on-rails

Question

I'm deploying a Rails app to Digitalocean. I'm working with Apache and Passenger. I was able to run my app locally in production and worked fine. I had the same problem on localhost but did the following things to make it work. Locally I work with Webrick server and in Ubuntu with Apache.
Installed these gems:
therubyracer
execjs
I added this to production.rb
config.serve_static_files = true
config.assets.compile = true
config.assets.precompile = ['*.js', '*.css']
Then I did
RAILS_ENV=production bundle exec rake assets:precompile
I tried the same for production in Ubuntu and everything seems fine but the images.
This is what I have in /etc/apache2/sites-available/metalmind.com.co.conf
<VirtualHost *:80>
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.
#ServerName www.example.com
ServerAdmin something#hotmail.com
ServerName metalmind.com.co
ServerAlias www.metalmind.com.co
DocumentRoot /home/luisjar/Metalmind_2/public
<Directory "/home/luisjar/Metalmind_2/public">
Options All
AllowOverride All
Require all granted
</Directory>
# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the loglevel for particular
# modules, e.g.
#LogLevel info ssl:warn
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
# For most configuration files from conf-available/, which are
# enabled or disabled at a global level, it is possible to
# include a line for only one particular virtual host. For example the
# following line enables the CGI configuration for this host only
# after it has been globally disabled with "a2disconf".
#Include conf-available/serve-cgi-bin.conf
</VirtualHost>
# vim: syntax=apache ts=4 sw=4 sts=4 sr noet
I appreciate any help here.

For images to load in production , you need to check certain things -
1) What's the url being generated where you see no image loaded (Use firebug to see the url path)
2) Where are you storing your images , is it under images or under public folder .
3) Have you precompiled you assets for production using this command (rake assets:precompile RAILS_ENV=production)
Also , in cases like these logs are quite helpful too .
